Front

What is the slope in a linear equation?

Back

The slope is a measure of the steepness of a line, calculated as the rise (change in y) over the run (change in x).

Front

What is the pattern of the sequence: 0, 2, 4, 6, 8, ?

Back

The pattern is +2, meaning each number increases by 2.

Front

What is the next number in the sequence: 2, 4, 8, 16, ?

Back

The next number is 32, as the pattern is to multiply by 2.

Front

Define 'linear equation'.

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does 'rise' refer to in the context of slope?

Back

Rise refers to the vertical change between two points on a line.

Front

What does 'run' refer to in the context of slope?

Back

Run refers to the horizontal change between two points on a line.

Front

What is the formula for calculating slope?

Back

Slope (m) = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What is a sequence in mathematics?

Back

A sequence is an ordered list of numbers that follow a specific pattern or rule.

Front

What is the next number in the sequence: 1, 3, 5, 7, ?

Back

The next number is 9, as the pattern is +2.

Front

What is the next number in the sequence: 5, 10, 15, 20, ?

Back

The next number is 25, as the pattern is +5.
